某冷轧厂排放的废水中污染物种类多、浓度高,且废水水质水量变化较大,属高浓度、难降解废水。经采用双膜法对废水进行深度处理,系统运行稳定,脱盐率达96%以上,出水水质满足循环水补充水要求,废水回收率达65%以上。本文对该处理系统超滤、反渗透等的运行效果进行了叙述和分析。
某冷軋廠排放的廢水中汙染物種類多、濃度高,且廢水水質水量變化較大,屬高濃度、難降解廢水。經採用雙膜法對廢水進行深度處理,繫統運行穩定,脫鹽率達96%以上,齣水水質滿足循環水補充水要求,廢水迴收率達65%以上。本文對該處理繫統超濾、反滲透等的運行效果進行瞭敘述和分析。
모랭알엄배방적폐수중오염물충류다、농도고,차폐수수질수량변화교대,속고농도、난강해폐수。경채용쌍막법대폐수진행심도처리,계통운행은정,탈염솔체96%이상,출수수질만족순배수보충수요구,폐수회수솔체65%이상。본문대해처리계통초려、반삼투등적운행효과진행료서술화분석。
The wastewater discharged from a cold -rolling mill contains more pollutants at high concentrations, and the quality or quantity of wastewater changes greatly was a high concentration of difflcuh biodegradable wastewater. Depth treatment of wastewater by using double - membrane method operate stable, desalination rate of 96% or more, water qual- ity met the supplement water requirements of circulating cooling water, wastewater recycling rate of 65% or more. The op- eration effects of UF ＆ RO was described and analyzed.
